Background: Hip osteoarthritis (OA) is a major cause of pain and disability that results in considerable social and medical costs. Mechanics such as posture, alignment and orientation of the hips and the spinal column and the relationship between these factors have been implicated in the development of both hip and spine pathologies. This study aims to test the hypothesis if pelvic incidenc...

Methods One-hundred thirty six volunteers (male:34, female:102, mean BMI=21.1) who have no history of spinal diseases were enrolled. The average age was 39.5 years (20 ~ 69). Spino-pelvic alignments (T1/T12 kyphosis, Lumbar Lordosis [LL], Sacral Slope [SS], Pelvic tilt [PT], Pelvic Incidence [PI], T9-hip axis sagittal angle [T9ang], and sagittal vertical axis [SVA]) were measured using the EOS ...

  Background: Pelvic ring injuries and sacroiliac dislocations have significant impacts on patient’s quality of life. Several techniques have been described for posterior pelvic fixation. The current study has been designed to evaluate the spinopelvic method of fixation for sacroiliac fractures and fracture-dislocations.   Methods: Between January 2006 and December 2014, 14 patients with sacroi...

BACKGROUND Recently, a grayscale inversion view was reported to improve intra- and inter-observer reliabilities in measuring coronal curvature with Cobb and pedicle methods in scoliosis patients. However, the grayscale transformation has never been applied to the measurements of spinopelvic parameters. The purpose of this study was to compare the measurement reliabilities of the spinoplevic sag...

OBJECTIVE The purpose of this study was to analyze the differences of spinopelvic parameters between degenerative spondylolisthesis (DSPL) and isthmic spondylolisthesis (ISPL) patients. METHODS Thirty-four patients with DSPL and 19 patients with ISPL were included in this study. Spinopelvic parameters were evaluated on whole spine X-rays in a standing position. The following spinopelvic param...

AIM Sacral fractures are generally seen together with pelvic ring fractures. They can also develop in isolated form rarely. Instability is observed in these fractures in rates reaching 30%. MATERIAL AND METHODS Spinopelvic stabilization was applied to 10 cases with pelvic fractures together with sacral fractures and spinopelvic instability. Two cases were treated with adductive screws extendi...

OBJECTIVE To investigate the relationship between bone mineral density (BMD) and sagittal spinal balance in the Korean elderly population. METHODS The retrospective study included subjects aged 60 years and above, who had whole-spine lateral radiography and dual-energy X-ray absorptiometry (DEXA) within a year's gap between each other. Sagittal vertical axis (SVA) for evaluation of sagittal s...
